SMOKERS PIPE.

' Application led .'l'une 7, 1926. Serial No. 114,086.

Our invent-ion relates to pipes for smoking tobacco and one of the objects of the invention is the provision of a pipe which is readily cleaned.

Another object of the invention is the provision of a pipe which will not become foul due to the absorption of extract from the tobacco.

Our invention possesses other objects and features of advantages some of which with the foregoing will be set forth in the following description of our invention which is illustrated in the drawings forming part of the specification. It is to be understood that we do not limit ourselves to the showing made by the said description and drawings as we may adopt variant forms of our invention Within the scope of the claims.

Referring to the drawings:

Figure 1 is a vertical sectional view of our pipe.

Figure 2 is a plan View of the bit and inner stem. The direction from which the view is taken is indicated by the arrow 2 of Figure 1.

Figure 3 is a vertical sectional view of a portion of the inner stem. Only a part of the stein is shown and the direction of the view is the same from which Figure 1 is taken.

ln broadly descriptive terms the pipe of our invention comprises a bowl in which the tobacco is adapted to be placed and formed with a stein thereon preferably integral therewith and lined or bushed with a thin cylindrical tube. A bit or mouth piece is also provided on which is carried an inner stem thru which and the bit extend the usual smoke passage. The inner stem is adapted to snugly seat within the liner of the bowl stein, and eX tending across the inner stem so as to intersect the smoke passage therein, is a recess which not only provides a space in which conf densates and juices may lodge but which results in a head or scraper which scrapes the bowl stem clean when the bit and inner stem is withdrawn. The inner stem may then be wiped clean with the utmost convenience because of the open character of the part, and with the replacement of the bit and inner tube, a clean and sweet smelling pipe is presented.

More particularly our pipe comprises Ia bowl 2 of any suitable material and provided with the usual combustion chamber and which is provided with the stem 37 preferably integral with the bowl. Fitted permanently into the bowl stem is a bushing or lining 4 preferably formed of thin gage aluminum tubing'. This lining is not an essential feature of our invention but we prefer to use it because it provides a better seat, for the inner stem and because it provides a metallic surface which of course is not absorbent.

Snugly fitting within the lining 4 is the inner stem 6 having the threaded nipple 7 for attachment to the bit 8. A smoke passage 9 extends longitudinally thru the bit and inner stem. The endv 11 of the inner stem is formed on a slant as shown in the drawings so as to conform approximately with the shape of the bottom lof the combustion chamber, the proportion of the parts being such that the inner stem reaches thru the outer stem and to the bowl as shown in Figure 1 of the drawings.

Extending across the inner stem and intersecting the smoke passage is a recess 12, which as indicated in Figure 1, provides a catch basin in which condensates and other waste results from smoking may accumulate. The inner stem is preferably made of aluminum and since the liner is also metallic, there is no absorption of these waste products and they remain until removed. The formation of the recess 12 leaves a head 13 on the end of the inner stem, and this head functions as a scraper when the inner stem is removed by tension on the bit. Preferably the recess is so formed that a scraping edge 14 is left on the head 13 and preferably too, a slight bead 16 surrounds the aperture of the smoke passage nearest the bit so that condensates forming on the walls of the recess will not drain down into the smoke passage and be drawn into the mouth of the smoker.

It will be noted that the recess 12 leaves a rather thin and readily bent wall 17 connecting the scraper head 13 with the main body of the inner stem. This thin wall makes it possible to slightly bend the inner stem in the event the joint with the liner becomes loose. A very slight bending serves to tighten the joint between the inner stem and the outer stem.

It will be noted that the construction of our pipe permits a ready separation of the inner stem from its seat in the outer stern and that as it is withdrawn the scraper head necessarily carries all accumulation in the recess 12. The inner stem may then be wiped clean with any convenient material and reinserted in the outer stein. Since the condition of a pipe as to cleanliness and odor is entirely vdependent upon the prevention of absorbed tobacco products and the accumulation of ilth therein, it will be readily seen that our pipe construction lends itself readily to cleanliness and a sweet smoking pipe.

We claim:

l. A smokers pipe comprising a bowl including a combustion chamber and having a stem, a bit, and an inner stem carried by the bit and seating in the bowl stem, said inner stem having a straight smoke passage terminating in the side of the combustion chamber, and said inner stem also having a recess in the lower side thereof intersect# ing the smoke-passage to provide a catch basin and a scraper head on the inner stem.

2. A smokers pipe comprising a bowl including a combustion chamber and having a stem, a metallic liner in the bowl stem, a bit, and an inner stem carried by the bit and scating snugly within the liner, said inner stem having a straight smoke passage termin ating in the side of the combustion chamber, and said inner stem also having a recess in the lower side thereof intersecting the smoke passage to provide a catch basin and permit deforming of the inner stem to insure a snug iit between the inner stem andthe liner, and a scraper Ihead on the inner stein.

3. A smokers pipe comprising a bowl including a combustion chamber and having a stem, a bit, an inner stem carried by the bit and seating in the bowl stem, said bit and inner stem having alined passages, and a scraper head on the inner stem through which said passage extends to terminate in the side oit' the combustion chamber.

4. A smokers pipe comprising a bowl having a stem, a bit, and an inner stem carried by the bit and seating in the bowl stem. said inner stem having a straight smoke passage terminating in the bowl, said inner stem also having a recess in the lower side thereof intersecting the smoke passage, and a bead surroundingy the intersection of the smoke passage nearest the bit.

In testimony whereof, we have hereunto set our hands.
